I remember reading somewhere that your battery won't charge if it's already above 95%. So to get it to get up to 100%, you have to unplug it and discharge it fully and then let it fully charge back up without interruption.
Take a look at the instructions for battery calibration in the MacBook manual.

He did. He let it run all the way down till it was completely drained, and then charged it back up.

Go to www.coconut-flavour.com and download and install coconutbattery v2.5. It'll tell you your Original battery capacity as well as your current battery capacity among other things. Very handy. Right now, my Macbook's original capacity is 5260mAh while my current capacity is 5280mAh. My Macbook is 4 weeks old and I calibrated the battery during my first week with it so it's in good shape.

Sorry for barging in but I was wondering...
I'm usually near a power socket whenever I settle down to do some work, so if I leave my MBP plugged in all the time will that cause any issues with battery life in the long run?

In the long run you would likely diminish the carrying capacity of your battery. You should calibrate it regardless if you have it plugged in all the time or not. You should be fine doing once a month but anyone can correct me if my time is wrong as I'm a new Macjunkie.

Haha, hard to say! I would like to think it is just my good luck to get a superbattery yet you're probably right. In any case, the battery does seem to last a long time for me.

The coconut battery actually doesn't do anything except display already available information in a pretty interface. It gets the information from the System Profiler. So if the software is bad, it's Apple's software that is bad.

My macbook pro is only 12 months old, 96 battery cycles, but its capacity is now reduced to 24%.
It shutdowns quickly without system information, and re-calibration processs does not work.
What is the issue ?
a wrong serial ?
